First of all, I'm new to servers. I've installed Windows Server 2008 x86 on an old PC and played with it, created a couple accounts, OUs, roles etc.
I would like to revert it all back to the state when I installed it (plus keep the Windows updates - if possible).
Is that possible to do? Or do I have to manually remove all the things I did (I'm not even sure that I remember all since I was playing with it quite a while ago).
